Description

When printing gyroid or mesh infill on the Bambu Lab A1, the printer can vibrate quite a lot and cause the filament spool to unwind by itself.
This creates loose filament loops which may later tangle or feed badly.

So I made this simple fork that mounts on both sides of the spool and reduces spool wobbling and uncontrolled filament unwinding.

It does not lock the spool and adds almost no resistance.
It simply stabilizes the spool enough to keep the filament under control.

Tested on long gyroid prints where the filament previously kept unwinding by itself.
